One that has been around for a long time is the watch. We have seen the watch evolve over time and become something completely different. I remember my first watch when I was young was a Casio BabyG, which only had the time, date, and you could set an alarm, you also had a light so you could see the time in the dark. Now we have the iWatch, where you can still check the time, set alarms etc, but now you can also check your emails listen to music- basically everything that can be done on your smartphone. And all this happened within my 20 years. This shows the depth of wearable technology, as well as how we evolve as humans, and over time, so do our technologies.

Now there are wearable technologies that I had not even heard of, until I started doing my research.

The intelligent tattoo, developed by John A. Rogers, is an electronic "tattoo" that can attach to human skin and which has the flexibility and durability to stay there for a couple of weeks. It is being used to measure muscle and brain activity.

Motorola is working on skin-based stickers and ingestible pills, to improve versions of authentication for secure areas- the person's body becomes part of a password.

I definitely think that a lot of people could benefit from this kind of technologies. I can see the intelligent tattoos being used in the field of medicine. Where patients could use them so that the doctors can see their progress through the data. It could also be used to study sleeping patterns and dreams, research that is not entirely conclusive. It could be used in experiments to learn more about the human body and help determine how muscle and brain activity fluctuates in various scenarios. 

I wonder how these could evolve and become more developed, and maybe even more attainable, and useful for the larger population. An example that came to my mind is, drinking water. I've noticed people do not drink as much water a day as they are supposed to, which is odd to me because I always have a water bottle in hand- I wonder if this technology could detect that the individal's water intake of the day is low, or are hydrated, and send them a reminder to drink water? 

Seeing as they are still in the early stages, I can only imagine how far these wearable technologies will go.
